Question about Windows 7-64 bit and ram

Recently bought a Dell XPS 8500 running Windows 7-64 bit directly from Dell. Had been using XP for years on HP computers so no clue about Windows 7 or 64 bit and very little dealings with Dell. I have a question about RAM and Windows 7/64. Does 7/64 actually double the amount of RAM? In both my order confirmation from Dell and in the packing slip it states "8GB DDR3 SDRAM at 1600MHZ-2x4GB. However, system scans show that I have 4GB of Ram with 3 slots open. Opening the case confirms the latter. I called Dell and the technician told me that in Windows 7/64, RAM is doubled so I essentially got the 8GB I ordered. I kind of scratched my head but did not argue. Shouldn't there have been 2-4GB and then if doubled the equivalent of 8GB? I wanted to check around before I called Dell back. (Got this computer 7/20/2012). Thanks for any input.

64-bit Windows does not "double" the memory. It does however allow the system to recognize more than 3gb of RAM, which was a limitation of the 32-bit OS. If you open the case, and there are TWO modules in there, I would pull one out (with the system off, of course) and it should indicate that it is a 4gb module. With two of them, you have your 8gb. If it only says that it's a 2gb module, then two would make 4gb, and you got jipped.

The "2x4gb" means there are two modules with 4gb on each module, for a total of 8gb.

I called Dell and the technician told me that in Windows 7/64, RAM is doubled so I essentially got the 8GB I ordered.

If you got that technician's name report him/her to Dell. Making an occasional mistake on an order is understandable, and as Krishna posted Dell will correct the mistake, but that technician's statement is inexcusable.

Thanks for the replies. I called Dell back and after sending them my system configuration they agreed that a mistake had been made regarding what was actually shipped. I received the additonal ram yesterday (7/27). The tech also apologized for the "misunderstanding" regarding the supposed doubling of ram in Windows 7/64. But now I am even more dubious. I asked about increasing my ram from 8 to 16gb but Dell told me that additional ram was not available. I said not available to upgrade when it was stated that it was expandable to 32gb. The tech told me the ram for the XPS was out of stock. I asked where they got the 4gb they were mailing to me. I got silence and the repetitive answer. Ram for the XPS is out of stock. Why not send me 2x4gb of the same ram with the replacement? Silence and then again told it was out of stock. As an aside the xps 8500 is not even shown on their support website and no compatible ram is shown on their site where you can order ram. For the xps 8300 and other desktops but nothing about or for the 8500. I appreciate the ram correction but not starting off well with Dell.

Thanks for the reply and info. I'm familiar with crucial having bought ram for my HP a while back. And I saw Ram there that they say is compatible with my Dell after Dell told me they were out of stock. I think I'm just venting and expressing negatives and frustrations about my dealing with Dell so far. Thanks again.

That's not unique to Dell. All big-box manufacturers are exactly the same. The profit margins on computers is so thin that they immediately lose money with just 1 or 2 tech support calls. That's why HP wanted to get out the business entirely. They're not making any money with it.
